Application tiled November 4, 1902. Serial No. 130,049. (No model.)

Be it knownthat I, JAMES H. HERRON, a citizen of the United States,residingat Erie, in the county o-f Erie and State of` Pennsyl- Vania,have invented certain new and useful Improvements in Air Compressor-Cylinder Water-Jackets; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as willenableothers skilled in the artto which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

My invention relates to air-compressor-cylinder water-jackets, and hasfor its object the construction of a cylinder and the water-A jacketthereon in such a manner that Water entering at a central point at thelower side of the cylinder passes both ways along the lower half thereofand through openings into jacketed cylinder-heads and thence throughopenings back along the upper halfof the cylinder to and ont of anopeningat a central point at the top of the cylinder, thus insuring aconstant circulation of water from the time it enters the jacket untilit leaves it.

The features of my invention are hereinaf-H ter set forth and explained,and illustrated in the accompanying drawings, in whichM Figure I isanend view of an air-compressor cylinder embodying my invention.

so as to divide the lower half ot' the waterchamber vertically, so as toform two cham- At the junction of the waterchambers B and B2 there is awater-inlet E, which opens into the chambers B and B2 at each side ofthe annular rib a', as shown in Fig. 2, so that water entering therebyflows into both the water-chambers B' and B2. In the flanges A and A2 atthe ends of the cylinder I make Openings d cl', leading from thewater-chambers B' and B2 into the lower portions of the water-chambers Dand D' in the cylinder-heads C and C', and through the flanges A and A2,I also make openings d2 and cl3, leading from the upper portions of thechambers D D into the water-chamber B2 between the upper half of thecylinder A and the jacket B, these openings d, d', d2, and d2 beingclearly shown in Figs. 2 and 3, and at the top of the central part ofthe water-chamber B3, I provide a water-outlet E.

In operation water entering at the waterinlet E passes in at each sideof the rib ot into the chambers B and B2 and travels along the lowerhalf of the cylinder A to and through the openings d d into the lowerparts of the Achambers D D and thence back through the openings (Z2 andd3 into the outer ends of the chambers B3 and thence longitudinallytoward the center of the chamber B3 .and out through the water-outletopening E". Thus a complete circulation of the water entering at E iskept up until it passes out at E', thereby subjecting all parts of theperiphery and heads of the cylinder to the cooling action ofconstantly-changing currents of water.

Having thus described my invention, so as to enable others to construct`and utilize the same, what I claim as new, and desire to secure byLetters Patent of the United States,

l. The combination of an air-compressor cylinder, radially-projectingflanges on the ends thereof having openings therein, chamberedcylinder-heads secured to said flanges and communicating with theopenings therein, a water-jacket having water-inlet and water-outletopenings therein surrounding said cylinder and secured to theperipheries of the flanges thereon, longitudinal and annular ribsbetween the cylinder and waterjacket whereby the water entering theinletopening of the water-jacket is compelled to travel predeterminedpaths along the cylinder and through the cylinder-heads before passingout of the outlet-opening in the waterjacket, substantially as and forthe purpose set forth.

2. The combination of an air-compressor cylinder having openings throughthe anges at the ends thereof, a water-jacket surrounding said cylinder,chambered cylinder-heads in said cylindercommunicating with the openingsin the ilanges thereof longitudinal ribs between the cylinder and thejacket at each 'JAMES H.
